Here are my solutions.
There should be some backroutes.
I would agree with Gronkling as I think the pack is not too hard and the biggest improvement would be the visual departement.
Also, a few level just had too many lemmings for their own good. If the level is already finished and there are still like 20 lemmings inside the hatch it's a good sign that that number could be a little bit lower.
The biggest thing I found was as I noticed that in a new level my replay for the last level started playing:
- Most levels levels share the same level ID! You can still change the level ID inside the editor by loading the level, clicking on the "Random ID" button in the "Global" tab and saving it.
If you create a new level always click on new level in the editor and be sure you get a new ID!If all levels have more or less the same idea the replay system can get really messy.
